Public bug reported: Booting an ARM64 SynQuacerâ„¢ E-Series software development machine with the 5.8 kernel will fail to configure the SATA drives DMA range correctly because of a regression caused by commit 7a8b64d17e35 ("of/address: use range parser for of_dma_get_range"). Currently invalid CPU addresses are not being sanity checked causing this issue.
The fix: Upstream linux-next commit: commit f49c7faf776f16607c948d852a03b04a88c3b583 Author: Colin Ian King <colin.k...@canonical.com> Date: Mon Aug 17 12:32:08 2020 +0100 of/address: check for invalid range.cpu_addr ** Affects: linux (Ubuntu) Importance: High Assignee: Colin Ian King (colin-king) Status: In Progress ** Affects: linux (Ubuntu Groovy) Importance: High Assignee: Colin Ian King (colin-king) Status: In Progress ** Changed in: linux (Ubuntu) Status: New => In Progress ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Colin Ian King (colin-king) ** Also affects: linux (Ubuntu Groovy) Importance: High Assignee: Colin Ian King (colin-king) Status: In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892138 Title: DMA config issues on Synquacer ARM64 platform cause SATA configuration failures on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1892138/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
